2. I also feel cheated by textbooks and various exercise books. Now I feel that the focus of the textbook is only a principle, which is very shallow. This exam is not as good as the basic exam. So the following key is how to use it flexibly after deeply understanding the content of the textbook, rather than memorizing it.

3. I haven't worked out the problem of n (D 1) either. Calculators suck. And I always thought that the topic would be given to N(d 1)N(d2). N(d 1) calculation needs integration, because it is cumulative probability distribution, but I don't think that stupid X calculator in windows can realize the integration function. Next time, I decided to remember several common values of N(d 1) for approximate estimation.

I did badly in the exam, too. Now I feel that kung fu can't get off the stage for this exam. Books are just the beginning. You must improve yourself in other ways. Think about what knowledge you need to be a qualified futures information/analyst, then find out this knowledge, and then calm down and improve a little, and the result will naturally not be bad. 165438+ Fight again in October! * * * Encourage.
